how to turn one lead into four leads?

I don't do this for a living so I thought I'd get some opinions from those of you who do. I'm adding a few electrical accessories to my motorcycle. For arguments sake, lets say I'm adding four accessories and each will have it's own relay. I want each relay to be triggered by the same switched source and I want each of the trigger leads (the wires coming from each relays "85" post) to share one side of a four pin Delphi connector. What is the best way for me to spread the single trigger lead among the four pins in the opposite side of the Delphi connector? In other words, how do I turn on lead into four leads? Obviously, I can think of ways to do it, but I'm wondering what is the best/proper way. Thanks. Tipsy
